Title: Improvements in and relating to electric transformer cores
IPC: H01F27/245
Filed: 1924-12-24
Abstract: 227,105. British Thomson-Houston Co., Ltd., (Assignees of Burnham, L. H.). Dec. 31, 1923, [Convention date]. Transformers.-A transformer core built up of laminations secured together by insulated bolts 8 passing through them is provided with ventilation ducts 10 extending through the portions of the cone which are shielded from the magnetic flux by the bolts. The ducts may be rectangular, as shown, or they may taper to a point midway between successive bolts, so as to conform roughly to the limits of the shielded portions. In another construction, the bolt holes 9 are extended in the general direction of the flux into the shielded portions to provide the ventilating ducts, openings being made in the bolts to permit of the circulation of the cooling medium between the ducts on opposite sides of each bolt. The core may also be divided longitudinally into two parts separated by spacers 6 to provide a passage 7 admitting the cooling medium into the interior of the core.

Title: Improvements in methods and apparatus for reeling wet rayon
IPC: B65H54/54

Abstract: 450,915. Reeling-machines. VISCOSE CO., Marcus Hook, Pennsylvania, U.S.A.- (Assignees of Allen, G. M. ; Moylan, and Long, F. F.; Chester, both in Pennsylvania, U.S.A.) Nov. 12, 1935, No. 31304. Convention date, April 10. [Class 120 (ii)] Wet rayon which has been spun by a wet-spinning process into a cake is led on to a swift of skeleton construction, and passage of air radially outward between the supports of the swift is prevented by maintaining a flexible impervious band over the supports and under the yarn during the reeling operation whereby concentration of acid and crystallization of salts are avoided. The band may be endless and of smooth external surface, and it may be of the same width as the length of the yarn supports of the swift. It may be secured permanently to the supports and move inwardly with the supports when the swift is collapsed. The band may be of rubber. The skeins may be wound in open diamond fashion and laced, or wound to form closed packages. For the subsequent wet treatments the wound yarns are removed from the swifts and wrapped preferably in knitted rayon fabric having the wales in the direction of the yarn of the skeins. As shown in Fig. 4, a skein 12 is wound on an impervious band 10 secured round the bars 7 of a swift. The band is flexible and may be cemented or vulcanized to the bars 7. Fig. 3 shows the swift in collapsed position. The arms of the swift are pivoted as shown. Two or more skeins may be wound on a single swift. Specification 450,914 is referred to.

Title: Improved processes and apparatus for casting metal ingots and to the castings produced thereby
IPC: B22D7/00
Filed: 1936-11-19
Abstract: 466,334. Casting ingots. ERICHSEN, A. M. Nov. 19, 1936, No. 31729. [Class 83 (i)] Moulds ; castings, extracting.-The cooling of an ingot of iron, brass, &c., cast in an open horizontal mould is regulated so that it all solidifies at about the same time by a cooling device in the bottom of the mould. The mould bottom a, which may have a concave face a<1>, and its central portion of copper and edges of a poor conductor, is cooled by fluid circulated through a jacket f which may have a baffle e adapted to concentrate the flow near the centre of the bottom a which it may support by means of small projections. The walls b, may be of chamotte, iron nickel alloy or other poor conductor, are interchangeable for different sizes and shapes of ingot, and are preferably shaped to give an ingot with rounded or sloped corners c, Fig. 12, which, after rolling, has a nearly rectangular form. The jacket f may be formed in a frame c, rotatable, as by means of a hand-wheel h and worm gearing, to tilt the mould when commencing to pour so that, on resuming the horizontal position, the bottom a may be covered quickly, to oscillate the mould through an angle, limited by a slot i, Fig. 2, and removable pin k, during solidification, to tilt the mould slightly so as to produce a slightly tapered ingot for easier insertion between reducing rolls and to invert the mould for extraction of the casting. In a modification the jacket f may have two or. more moulds a, Fig. 3, to be used successively, walls c<1> being provided for cooling liquid, preferably introduced after complete or partial solidification. The upper face of the ingot may also be cooled by sprinkling with water, by air blast, or by a fluid cooled bar v, Fig. 5. A cover with a central opening may be used to reduce the rate of cooling of the edges of the upper face of the ingot or a closed cover for allowing the solid casting to cool in inverted position. The moulds may be subdivided by fixed or removable frames or a number of moulds may be arranged side by side. If desired the bottom a may be shaped to produce an ingot with a slight taper near one end. The edges of the ingot may also be heated by steam or hot or combustible gas.

Abstract: 1,049,855. Applying capsules. FORDS (FINSBURY) Ltd. Aug. 20, 1963 [Aug. 21, 1962], No. 32104/62. Heading B8T. A capsuling apparatus of the kind including at least one capsuling head having a liquid containing chamber which is disposed between a flexible diaphragm 4 and a body part 2 and into which liquid under pressure is supplied to deform the diaphragm and thereby compress the capsule on to a bottle neck inserted into the cavity defined by the diaphragm, has one valve 10 associated with each head the valve being opened by the actuation of an associated member, e.g. plunger 12, in the head when the bottle neck is inserted, and means operative independently of the member to provide for closing of the valve and opening of the chamber outlet when the capsule has been compressed on the bottle neck. The apparatus may comprise a plurality of heads 19 vertically slidable on a platform 18 rotating about a shaft 10, the heads being pressurized from a single pump 37 receiving liquid from a reservoir 38. In each head a plunger 26 is slidably mounted to move upwards and actuate a lever 63 and so close a microswitch 62 when a bottle is inserted into the head by a ram mounted on a table beneath the platform. A solenoid-operated three-way valve 28 is located above and rotates with each head and electric current for energizing each solenoid is supplied through the normally open micro-switches and through a slip ring arrangement 61. The slip ring arrangement comprises carbon brushes 78 which rotate with the heads, all but one being in contact with an interrupted slip ring 73, and the remaining brush being in contact with an uninterrupted ring 72 and providing a common connection for all the valves. The brushes are arranged to be in contact with ring 73 when the bottles are inserted into the heads to effect energization of the solenoids and thus apply liquid pressure from chamber 29 through pipes 50 and hoses 52 to the liquid chambers 3. Each solenoid is de-energized upon its brush moving off the ring, valve 28 then shutting off the liquid supply and connecting each hose to a pipe 55 which directs the liquid into an annular trough 56 from where it is delivered to the reservoir 38.

Strip handling apparatus comprises an uncoiler for rotatably supporting a strip to be uncoiled incident to processing thereof, drive means associated with the uncoiler for rotating a coil supported by the uncoiler to cause recoiling of a length of uncoiled strip, shear means spaced from said uncoiler and adapted to sever said length of uncoiled strip while a portion of the strip remains in coil form and supported by said uncoiler, and strip bending means arranged between said shear means and said uncoiler and adapted to induce a permanent set into at least a portion of said length of uncoiled strip in a manner that in recoiling, a substantially selfsustaining coil is formed. Strip is unwound from a coil A supported by driven cores and passes over a platen 25, adjustable by pistons and cylinders 26, 27, through pinch rolls 43, 44 to the rolls 11, 12 of a mill 10. When the trailing, scrap, end of the strip starts to unwind, the mill 10 is decelerated and the strip is cut by a shear 46. The mill 10 is then reversed or opened up, the pinch roll 43 raised and the strip extending back from the shear to the coil is rewound as the uncoiler is driven in reverse. Prior to this upper, driven, bending rolls 31, 32 on an arm 37 are lowered on to the strip and a lower roll 33, which may be driven or idle, on an arm 34 is raised to co-operate with the rolls 31, 32 to form a permanent set in the strip to aid recoiling. The rewound coil is removed by a jib crane (22), Fig. 2 (not shown).
